Application tiled March ll., 1924.. Serial No. 633,39?.

My invention aims to provide an automobile vvheel of the general type known as disc Wheels and a brake drum therefor, and to save Weight and expense in such constructions.

The accompanying drawings illustrate i rangement.

f 'ot wheels.

Referring tothe embodiments-ot the invention illustrated, the driven hub 1 has fastened to it by bolts 2 the disc or annular 3. These discs are made oi various shapes and diametral section. At the outer edge the disc is formed With a rim d appronimately parallel with the anis oit the vvheel but slightly tapering tovvard the outer side oi the Wheel. 'lihe rim or axialgtlange out the vvhcel has at' its inside edge a transverse outward dange 5. rllhe demountable rim 6 which carries the tire is placed on the 'lange 4: oi the discand pressed up against the stop flange and is held there by means et lugs 7 arranged at intervals around the circumference. `Bolts 8 have heads 9 `tting in the angle of the disc 3 and flange 1, by which they are held against turninga the shanlr of each bolt passing through the disc 3 and the clip and their threaded ends being engaged by nuts 10 to force and hold the tire rim in place.

ll have providedl a very light and economi-- cal brake drum for attachment to this style It consists ot a simple ring or drum 11 formed by bending a straight strip of sheet metal of the Width of the drum such as can be stamped Without. Waste Jfrom a Sheet. One edge of this drum is ioined.y as by a butt welded joint 12 to the inner face of the disc 3. For the purpose o'f conven-' iently making such a butt Weld the disc is preferably stamped to form an annular rib 13 on its inner face fitting the edge of the brake drum.

Or the parts may be joined as in Figs. 2 Aand 3. Here the drum 11 has projections 14 at intervals extending through similarly spaced openings in the disc 3, and the' parts are held by additional metal 15 vdeposited over the ends of the projections 1t by the are weld or acetylene weld method. ln addition the edge et the drum 11 may be butt Welded to the rib 13 ii desired. The interlocking engagement by the projections 1li holds the drum positively against rotation on. the disc.,

According to liligl C the d isc isstarnped to form a rib lor the edge ont the brake drum and also a iiange 16 on the inner side and about 'which the drum 'il hte and by 'the latter is easily placed in accurate posiw tion during the operation o5 -Welding its edge to the disc. The Welding may be accom plished with or Without the interloclri'f rangement oi llig. F'Fne ioint ti made by butt Welding or by acetylene or f vvelding as indicated at 17 or by both de scribed in connection with Figs. 2 and The arrangement shown in Fig. 2 may strengthened by welding, either 'butt as in Fig. 1 or arcor acetylene vveldinp; f

with 4metal deposited in the corners vvhere the drum 1.1 meets the rib 13.

The disc of the vvheel may be stamped trom a single sheet as in the cases'illustrated or it may be made ot a plurality ci pieces as No. 698.400 which li have tiled., and in 'which this styleoi' disc is specifically claimed.

ylhe drum may be applied as described also to various other types ot Wheel.

'lhough ll have described with great pan voo 1 tor example in another application Serial" ticularity ot detail certain embodiments o? my invention, yet'it is not to be understood therefrom that the invention is restricted to the particular embodiments disclosed. "Various modifications thereof in detail' and in the arrangement of the parts may be made by those skilled in the art without departure trom the invention 'as defined in the 'ollovving claims.

-`What l claim is: i

1. rlhecombination of a disc Wheel, the disc being made of a continuous piece ot sheet metal `from centen to outer edge bent to form a .rib on its inner tace and 'a brake drum comprising a bent strip of sheet metal of substantially 'the width of the drum having its edge butt-Welded to the ribbed por tion' of the disc. v

2. The combination with a disc wheel ot a brake drum comprising a bent strip of sheet metal of substantiaily thel width of the drum comprising a bent strip of sheet metal drnm and having 011e edge bttWe1dd t0 of substantially the Width of the drum and the inner face 0f the disc, said disc being having its edge butt-welded to the ribbed 10 of sheet metal bent to form an inward proportion of the wheel. jection fting Within the drum. In witness whereof, I have hereunto 3. The combination with a metal Wheel signed my name. having a rib on its inner face of a brake THOMAS E. MURRAY.
